Trying to figure out dimensions for the pentair superflo impeller locking screw. Product # 355389 please help, driving me nuts not having pool up and ready.

Sounds like you are trying to get the standard fastener dimensions for that screw? If so, I've *never* seen a pool manufacturer supply that sort of data. I've occasionally purchased fasteners and O-rings as standards, rather than OEM, but I've had to carry the original part with me to an industrial supply house, and physically match OEM part to the standard part. I will note that impeller screw often seem to be specials, rather than standard parts. The threads are probably standard (except for the left-hand screws!) but the heads are not.
FYI, your part is #21 on this drawing:
